Tension Pneumothorax

In this article, we will discuss about Tension Pneumothorax. So, let’s gets started

Tension Pneumothorax

In tension pneumothorax, the mean pleural pressure is positive which means that air in the pleural cavity is under tension which causes compression collapse of the lung. It develops due to persistent air leak (air entry) inside the pleural cavity by the communication which opens during inspiration and closes during expiration preventing the air to escape. In this way, with each successive breath, the intrapleural pressure increases which eventually causes the mediastinum to shift to the opposite side and increased intrapleural pressure also puts pressure on the surrounding blood vessels.

There is decreased venous return to the heart and along with decreased cardiac output causing hypotension (cardiac tamponade) and cyanosis.

Clinical Features

Dyspnea, cough and acute exacerbation of pneumothorax symptoms

Trachea and mediastinum shifts to the opposite side

Decreased or absent breath sounds, there may be amphoric breathing present at a localized place.

Hyperinflated chest with decreased or absent chest wall movement of the involved side

Tachypnea, tachycardia, hypotension, cyanosis, and paradoxical pulse.




Clinical features of Pneumothorax

In this article, we will discuss about the Clinical features of Pneumothorax. So, let’s get started.

Clinical features

Chest pain ( Pain is sharp, pleuritic, and is localized to the same side of pneumothorax)


Fullness of intercoastal spaces

Decreased chest wall movement

Hyper-resonant percussion note

Decreased breath sounds, vocal fremitus, and vocal resonance in closed and tension pneumothorax. s

Increased vocal fremitus, vocal resonance, presence of whispering pectoriloquy (on development of large bronchopleural fistula), and amphoric bronchial breathing.

Accumulation of fluid or pus in the pleural cavity in case ocharacterized by f an associated infection (open pneumothorax or pneumothorax due to tuberculosis) along with physical signs of horizontal shifting level of dullness and succussion splash, and additionally there is signs of toxemia

Recurrent spontaneous pneumothorax occurs with emphysema due to the rupture of bullae occurring on the same side.
